SHADE-FIXTURE.

SPECIFICATION forming part Of Letters Patent NO. 298,128, dated May 6,1884-.

Applicationled September 11, 1883. (No modell) To a/ZZ whom it mayconcern:

Be it known that I, GEORGE W. STEELE, a citizen of the United States,residing at Paterson, Passaic county, State of New Jersey, have inventeda new and useful Improvement in Shade-Fixtures, of which the followingis a specification, reference being had `to the `accompanying drawings,forming apart thereof.

The object of my invention is to produce a curtain or shade roller ofnew and simple construction wherein by the use of a single pawl, incombination with a lock-plate, rod, spring, and detachable plug, theroller is automatically locked and held in any desired position, whetherin or out of the brackets, which will be hereinafter more fullyexplained. v

Figure I of the drawings is a front view of the shade on the roller.Fig. 2 is a section on line H II of Fig. 1. Fig. 3 is a longitudinalsection showing roller broken and an arrangement of devices. Fig. /lisan end View of roller and operating devices. Fig. 5 is a section on lineK K of Fig. 3. Fig. 6 is a'view of lock plate and band, part sectional.Fig. 7 is a bracket for the pin. Fig. 8 is a bracket for the rod, andFig. 9 is a front view of shade e represents a rod the inner part of vwhich is cylindrical, and is provided with a helical or spiral spring,m,which surrounds the cylindrical part n ofthe rod c, beinglongitudinally arranged thereon. rlhe innerrend ofthe spring m issecured in a detachable plug, p, at p, and the opposite end in the rodat a', the plug p serving as a bearing for the inner end of the rod e,as shown in Fig. 3. The roller a is bored out in the usual way, and therod c inserted,

The outer end of the rod e is constructed with flat sides, the lips ofwhich prorod and form shoulders against the lock-plate- The ,lock-plateb is constructed with lugs k and k2, which lugs are formed on the outerend or edge of the band of the lock-plate, which band or iiange projectsover the disk.

the projection or flange have inclined surfaces, at the ends of whichinclines so formed on the lugs 7s k2 are arrangedxnotches kf. The

lock-plate b maybe secured to the end of the roller by any of the knownmeans employed therefor. Y

To the side of the rod e, and outside of the locleplate, there issuitably pivoted a pawl, h, the inner lower end of which is arranged tobe in continual engagement with the lugs k and k2. rlhe upper inner endof the pawl, which is vertically arranged on the rod e, rests againstthe face of the lock-plate.

In practice the curtain or shade is secured to the roller by any of theknown means employed therefor, the brackets are placed in position inthe usual way, the roller cut to the desired length, and the plate c,having the pin el, secured thereto, the curtain or shade A is rolled upand the rod e placed in the slot e in l the bracket, and the'pin din thenotch d. The

curtain or shade is drawn downward by the hand, which action puts thespring m in tension. Y The engagement of the pawl h with the inclinedrising surfaces of the lugs la lcidis` tends the spring m longitudinallyoutward, which causes the inner top end of the pawl h to impinge hardagainst the disk of the lockplate, so that when the pawl 7L passes overthe end of the lugs 7c and k2 and reaches the notches 7c the spring m,which is distended by the action of the lugs 7c k2 on the pawl and rod,suddenly contracts, which action forces the engaging end of the pawl hinto the notches k', which locks the roller a, and prevents its furtherrotation until the same is manipulated by l the curtain or shade in theordinary way of lraising and lowering the same, and when so raised theinclined part of the lugs 7c lol will raise the engaging part of thepawl h above the opposite 'lug sufficiently high to cause the pawltopass over the notches 7c if a quick motion be given to the roller. Theinclined lips of the lugs 7c k2 are rounded off from the bottom of thenotches k upward to admit of the pawls raising out of the notch whenlowering the shade. The band b projects over the end of therollersufficiently to protect the devices. Illhe ribs and grooves forfastening the curtain are as shown.

said pawl in constant engagement with the lugs k k2 when said pawl isnot occupying; the notches 7c', the upper inner end of the pawl arrangedto impinge against the plate l), with r 5 the leek-plate b', plngp,spring m, roller a, and pin d, substantially as set forth.
